SEAN-COVER FASTENING FOR CAR-ROOFS.

Application filed July 21, 1915.

To all whom it vmay concern Be it known that I, Dwlolrr Munrnv, acitizen of the United States, and a resident of the city of Pittsburgh,in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvementin Seam-Cover Fastenings for Car-Roofs. ofwhich the following is a specification.

This invention relates to outside metal roofs of the type wherein theroof sheets extend crosswise of the Car and are connected along theirsidemargins by raised' seams formed by strips of metal which cover thespaces between adjacent roof sheets and whose edges overlap the sidemargins of the roof sheets.

The object of the invention is to secure the strips of metal which coverthe seams between the roof sheets without puncturing the roof andwithout the use of eavesclips or other securing means on the outside ofthe roof.

The invention consists in a sheet metal clip which is adapted to besecured to the car under a seam cover, and over which the seam cover canbe slipped endwise to embrace it and be held in position thereby.

Further objects and details of the 'invention appear in the followingdescription of the preferred form of the invention; and what theinvention consists in is more particularly delined in the appendedclaims.

In the drawings, wherein the same reference characters designate likeparts in the several views, Figure 1 is a planview of a portion of a carroof at the eaves, showing the end of a seam cover partly broken awaytoA disclose the clip; Figs. 9. and 3 are crosssections of the same onthe lines 2N2 and 3 3, respectively; and F ig. 4 is a perspective viewof a Securing clip.

The car roof shown in the drawings is applied to a car having wood roofsheathing boards 11, which are supported on the carlines, and which inturn support the roof sheets 12. The roof sheets are arranged side byside with wooden battens 13 between their adjacent edges. The edges ofthe roof sheets are provided with lip-standing flanges 14, which arespaced a little away from the battens to permit slight sidewise movementof the roof sheets. The top edges l of the flanges 14 are turned in andslope down toward the body portion of the respective roof sheets, andthese sloping edges 15 termi Specification of Letters Patent.

nate above said body portion at about half the height ot' the ilanges14. The ends 16 of the roof sheets may be turned under and hooked intothe rebent flanges 17 of the eaves flashing strips 18, which are securedalong the ea ves of the car from end to end.

The seam covers 19 are inverted channelshape, and are arranged over thebattens and root` sheet flanges with their side walls 20 turned in alongtheir bottom edges and up at their extremities, forming little troughs,the in'ner edges 21 of which are hooked under the edges 15 of the roofsheets. The side walls 20 and inner vedges 21 of the troughs are spacedfrom the roof sheet flanges so as to permit limited sidewise movement ofthe roof sheets. The ends 2:? of the seam covers are turned down overthe ends of the battens.

The seam covers are held in position on the battens by means of sheetmetal clips '23, which are nailed to the battons underneath the seamcovers. The clip Q3 has a central groove for the hatten, which is formedby pressing down wing portions .21 from the sheet metal on each side ofthe batten into parallel planes. `Thel side edges 25 of the clip arebent down to conform to the slope of the side walls 20 of the seamcovers, and in assembled position they fit snugly within the seam coversand hold them in cent-ral alinement with`the battens.

The seam covers can be slipped eudwise on and off of the retaining clips23. The ridge ends of the seam covers may be retained in position by thecorner caps with which outside metal roofs are usually held in place.The clips 23 bear loosely upon the tops of the flanges 14 and preventthe roof sheets from rising oflI the roof boards, while permitting themto move freely within the limits imposed by the battons 13 and the pivotbosses or other securing means usually provided at the ridge ends of theroot sheets.

The invention is not restricted to the forms and arrangen'ient of partsas shown and described.

lVhat I claim as my invention and desire to secure. b v Letters Patentis:
